The presupposition of the cartesian cogito provokes a ¿potential decrease of transcendental philosophy,¿ which means, that reevaluation of the scientific reflexive reason leads into a metaphysical evacuation. Original philosophical subjects develop into subjects of a scientific psychology respectively depth psychology. Two fundamental problems, resulting from this historical context of philosophy, should be described: Firstly the consciousness, which is objectivated and hardened as psyche by the influence of reflection. Secondly the unconsciousness, which seems like a hidden psychological entity with an indifferent essence. The effort to revise those two problems should be made by the use of phenomenological and existential philosophy. The intention of this revision is first to reintegrate the isolated reflexive consciousness in a field of consciousness and secondly to replace the confrontation with the unconsciousness by the dialogue with the fellow being.
